2 Claims.

My invention re1atesto tiling and more particularly to a tile provided with improved means for insuring a firm and unyielding connection between the tile and a wall or other base.

One of the objects of my invention is to provide a tile unit which is prepared prior to installation and which, by such preparation, is aiforded a rear surface perfectly adapted for anchorage to a wall. I f

Another object of my invention is to provide Ya tile unit which is equipped with anchorage means on its rear surface but without unduliY adding to its expense of manufacture. thereby insuring fa cheap and economical as well `as an efllcient tile unit.

Other objects of my invention will be apparent from the following description, it being understood that-the foregoing statement of the objects of my invention vis intended to explain L and not to limit itin any manner.

Fig. 1 is a rear view of my tile unit partly broken away.

Fig. 2 is a section along the line 2--2 of Fig. 1.

Fig. 3 is a section along the line I--I of Fig. 1.

Referring to the drawing, I0 represents the tile which is 'generally of a vitreous material, such as glass, and which may be colored or transparent.

The tile is provided with ribs Il over its rear surface. A tile ofthis construction is well known in theart and is ordinarily applied to a wall by a bonding material such as a plaster of Paris composition, the ribs vIl affording anchorage means for the bonding material. However, it is common knowledge that due to a variety of causes, the tile often separates from the bonding material destroying its utility.

According to my invention, a coat of ordinary paint .I2 is applied to the ribbed surface and this` specific compositionis unnecessary as long as the paint displays a binding quality as hereinafter explained. y

(Cl. 'l2-18) Over this coat of paint I2 and before it hardens, a layer of ordinary sand is applied either by spraying or pouring. The sand may be either fine or coarse, the size being immaterial as long as it is not smaller than 0.05 mm. diameter separated by means of Asieves, or as large as gravel. Generally, a size approximating 0.15l mm. diameter separated by means of sieves issuitable.-

As the paint hardens, the sand is more or less firmly embedded therein and the surplus sand is 10 merely shaken oil. When the paint has fully hardened the tile with its sand backing is ready., for use or may be stored or transported as desired.v

It is apparent that a tile thus prepared has a 15 rear surface that is admirably adapted for cooperation with a plaster mass to anchor the tile to a base since the roughest surface possible lmay be obtained by these means..

In addition to the provision of means-to retain go the sand. the paint l2 may serve another function. Should the glass tile I0 be transparent and uncolored, thepaint will be visible therethrough and novel aesthetic advantages may be combined with utilitarian advantages by my g5 process.

I have shown a preferred embodiment of my invention, but it is apparent that numerous changes and omissions may be made without departing from its spirit.

I claim:

1. A tile unit comprising a tile having acorrugated rear surface, a coating of paint applied to said corrugated surface, and a layer of sand4 covering saidcoat of paint, the granules of said $5 sand layer projecting beyond the outer surface of the coating of paint.

2. A tile unit comprising a tile having anirregular rear surface, a layer of paint applied to A said rear surface, and a layer of sand having its granules partially embedded in said layer of paint and substantially covering said .layer of paint.
